BED-JOINT.

SPECIFICATION forming part of Letters Patent No. 549,128, dated November 5, 1895.

Application filed May 14, 1895. Serial No. 549,224. (No model.)

To all whom it may concern.-

Be it known that I, HOWARD S. HART, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Bed-Joints, of which the following is a full, clear, and exact specification.

My invention relates to improvements in bed-joints; and it consists, essentially, in the improvement of the bed-plates commonly attached at the ends of the bed-rails and adapted to hook in or otherwise engage with the bed-posts.

The object of my invention is to produce an economical, light, and serviceable bedplate which shall possess great strength and which will fit the standard bed-rail slot.

In the manufacture of bed furniture it is customary to form in the ends of the bedrails slots of a standard size, and inasmuch as the wood portions and the slots therein are first produced by one manufacturer and the metal portions subsequently by other manufacturers it is essential that the plates adapted to be inserted into the slots in the bedrails be of the standard thickness, so as to fit snugly to prevent loose play.

By my invention plates may be made from thinner stock than ordinarily used; but the thickness of the bed-plates-that is, the distance between one outer face of the plate and the opposite outer face-corresponds to the standard gage, so that they will wedge tightly into place in the slots.

My invention is illustrated by the accompanying drawings, in which- Figure 1 is a side elevation of a bed-plate. Fig. 2 is a side elevation of a bed-plate and portion of a bed rail and post partly in section. Fig. 3 is a vertical cross-section of the bed rail and plate, taken on the line as 00, Fig. 2.

Similar letters refer to similar parts.

A is a bed-rail. B is a slotin the end of said bed-rail, adapted to receive the bed-plate.

D is a bed-plate having the ordinary hook projection E, adapted to engage the bed-post F. G is a corrugation in said bed-plate, by preference extending into that portion of the plate forming the hook E.

In practice the slots B in the ends of the bed-rails are usually of a standard size. The

plates D are made from metal of less thickso that if the slot in the bed-post F is of cor responding thickness the hook will fit snugly thereinto. This corrugation G not only takes up the loose play that would otherwise occur where metal of a thinner gage is used, but it also materially strengthens the plate, so that its capacity to withstand lateral stress is even greater than where the fiat thick plate of standard twelve gage steel is used. The plate D is held in place in the slot B by suitable pins By my invention twenty-five per cent. or more of metal may be saved, thereby reducing cost and weight without diminishing in any Way the strength of the plate.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a bed-joint, the combination of the siderails A having slotted extremities, with bed plates having hooked projections and with corrugations extending partially over that portion of each plate adapted to be inserted into its corresponding slot and partially over that portion of the plate constituting the the hook and the intermediate connecting portion between the plate and hook, said plate being made from metal of less thickness than the thickness of the slot, the corrugations causing the plate to assume substantially the thickness of the slot at the same time strengthening the connection between the plate and hook, substantially as described.
